When it comes to ground beef, among the most versatile and beloved of ingredients, itâs not all about meatballs and burgers and chili. Psh, who are we kidding, yes it is! Few things excite us more than a couple of pounds of fresh 80/20 chuck, straight from the butcherâs loving meat-grinder, ready for our bidding.
When oceanic and oceanic plates diverge it creates mid ocean ridges!
Making the world better, one answer at a time. At an oceanic subduction zone, the athenosphere is subducted under continental lithosphere, or under other oceanic lithosphere. Friction between these plates causes heat that creates magmas. At a divergent boundary upwelling mantle (athenosphere) decompresses due to reduced pressures, allowing magma to form. This magma is extruded onto the seafloor as pillow basalts, and beneath the seafloors as massive gabbros and sheeted (gabbro) dikes. At an oceanic subduction zone, the athenosphere is subducted under continental lithosphere, or under other oceanic lithosphere.
